Money

Lil Wayne and the IRS have something in common -- they both wanted millions from Birdman -- but only one of 'em got the Cash Money honcho to cough up the dough, and Weezy's not the one smiling.

The music mogul was slapped with two federal tax liens - - one in December 2014, the other in February 2015 -- for refusing to pay a total of $1,942,400.58 in back taxes.

Birdman quickly learned no one's more gangsta than Uncle Sam -- the feds threatened to snatch up his property and assets if he didn’t pay ASAP ... and within a few months, Birdman paid off the debt.

Maybe Wayne should ask the real OG's (our government) to get "Tha Carter V" released.

Chris Brown is at war with his baby mama, who claims he's stopped paying the measly $2,500 a month in child support, and now she's gunning for 6 times that.

Multiple sources connected with the couple tell TMZ, Chris has been paying baby Royalty's mom, Nia Guzman, the $2,500, but the gravy train stopped in March. Our Chris sources say he stopped paying because Nia demanded $15k a month, which he thinks is ridiculous.

We're told Chris says Nia's treating the baby like a winning lottery ticket, but she claims he's being incredibly cheap and their daughter is suffering as a result.

We're told Nia's lawyer, Carl Moore, will be filing legal docs in the next 2 weeks demanding back child support and a huge monthly hike.

NY Islanders Hall of Famer Mike Bossy is eyeing a legendary NHL puck on eBay, but refuses to pay a dime -- 'cause in his mind he's the rightful owner, and he's pissed someone's trying to sell it off.

Here's the deal ... in 1981, Bossy scored 50 goals in 50 games -- a feat only accomplished by 4 other players -- but about 30 years ago the treasured 50th puck slipped out of his hands.

We spoke to the eBay seller, Jake Jacobson ... a HUGE Islanders fan and former swim coach, who claims he ended up with the prized puck when Bossy's young daughter gave it to him as a thank you for her swimming lessons.

A couple years ago he contacted Bossy and offered to return it, but claims Bossy "didn't really seem interested." He says Bossy offered him a signed stick and that's about it. "He couldn't even meet. It just wasn't a good offer."

So, now Jacobson's gone the eBay route, and Bossy's ready to drop the gloves. The Hockey Hall of Fame and Museum -- which also wants the puck -- tells us, "Mike's position is, if the puck was mistakenly given to the seller, it's his rightful property. He shouldn't have to buy it back."

Bossy hasn't lawyered up, and Jacobson's pressing forward with the auction ... which ends Tuesday. Here's the thing ... his opening bid is $850, and he has ZERO offers.

Bobby Flay has taken an incredibly cheap shot at his estranged wife, telling the judge in their divorce case that any medical problems she has are the result of vanity ... specifically a boob job.

We're told as part of her argument to invalidate their prenup, Stephanie March says she's been plagued by well-publicized medical problems, including a burst appendix and 3 deep infections. As a result, she says she's unable to work as an actress and the prenup would create an undo financial hardship.

Bobby has responded to Stephanie's argument, but he got surprisingly detailed, saying the infections were the result of breast enhancement surgery. It's pretty clear the point he's making is that Stephanie's problems are her own doing ... choosing to go under the knife for the sake of vanity.

Stephanie also took a shot at Bobby, saying revelations of his alleged infidelity have compromised her health and mental state.

David Letterman's former employees didn't walk away empty-handed this week -- he dropped thousands of dollars hooking them up with ... wait for it ... custom-made letterman's jackets.

Letterman's final gift to his staff have the words, "Thank you and good night" scrawled across the front. Dave scooped up more than 200 of them ... according to the owner of Golden Bear Sportswear.

Dave's been buying staff swag from GBS for 15 years, and the owner tells us they were contacted last winter, after Letterman announced his retirement plan. She says Dave designed the jacket as a final gift.

GBS wouldn't divulge exactly how much Letterman spent, but the jackets run AT LEAST $300 each ... so you do the math.

Safe to say, Dave can afford it.

John Mayer just got his clock cleaned in a lawsuit in which he claimed he was defrauded by a watch dealer ... because John has not only dismissed his suit ... he now says his claims were false.

TMZ has obtained a joint statement between Mayer and Robert Maron, who sold the singer more than $600,000 worth of Rolex watches back in 2007. Mayer -- a big-time watch collector -- claimed the watches had counterfeit parts and Maron knew it.

Now we've learned Mayer has dismissed his lawsuit and no money or property changed hands. What's more, their joint statement says, "Two years of research restored John Mayer's belief that Bob Maron is an expert on Rolex watches, and confirmed that Bob Maron never sold him a counterfeit watch."

Maron's lawyer, Eric George, said early on he'd beat Mayer in court, but the dismissal is pretty much the same as a jury victory for Maron.

BTW ... Maron is best buds with Charlie Sheen and even had a co-executive producer title on "Anger Management."

Big time rappers Lil Wayne and Wiz Khalifa can try to step into Kaskade’s arena any time they want ... as far as he's concerned the rappers are only helping him make more money.

We got Kaskade at LAX, and asked him if he was worried about Weezy and Wiz putting him out of business now that they're dabbling in spinning.

Check out Kaskade's reaction to the "celebrity DJs" -- it's sheer bravado.

Mark Cuban suffered a slow, painful poker death at the hands of Tiger Woods, but wants to make it clear ... he's still got a few pennies left to invest on "Shark Tank."

Cubes tells TMZ Sports, Tiger did hit him hard during the charity poker tournament in Vegas last weekend, and says Tiger's secret weapon was being a "very patient" player. Odd, since Woods is known to be anything but than when he's stinking up a golf course.

And the Mavericks owner says, despite the hysterical video he posted of Tiger's poker face right after their game -- he didn't lose everything. He says, "We didn’t have any big bets like people made it seem."

In other words, Cuban was just billionaire broke -- as in, still filthy rich to the rest of us -- and only until he walked 20 feet to the nearest ATM.

Floyd Mayweather is flossin' a ridiculously rare man-bag ... and it costs more than your CAR!!!!

The boxer just touched down in Georgia this morning ... flaunting one of his favorite expensive purchases -- a diamond Hermès HAC 50 bag made out of crocodile skin.

We spoke to someone from Hermès who told us the bag isn't being sold in stores -- and therefore, it MUST be a custom job (Pharrell had a custom Hermès bag made in 2007).

So, we went to the The Money Team looking for answers ... and one of Floyd's top TMT guys told us Floyd paid around $150k for the bag, which is accented with 245 diamonds on the metal hardware.

It's a drop in the bucket for Floyd who claimed he made around $200 million for the Pacquiao fight.

And he's not done spending yet ... Floyd tweeted to his people in Atlanta -- "Anyone know what time the stores open up? I need to pick up a few items for the [Atlanta Hawks] game tonight."

O.G. 'Apprentice' bitch Omarosa Manigault isn't about to let some ‘Real Housewife' from Down Under rip-off her self-help book -- and now she's taking legal action to block the "bitch."

The ‘Apprentice’ vet served Pettifleur Berenger -- one of the "Real Housewives of Melbourne" -- with a cease-and-desist for her recent self-help book, "Switch the Bitch: My Formula to Being the Champion of Your Life, Not the Victim."

Sound familiar? Omarosa dropped her own motivational tome, "The Bitch Switch: Knowing How To Turn It On and Off" ... back in October of 2008.

Gotta say ... Omarosa and her lawyer, Bradford M. Cohen, fired off a pretty entertaining letter. They demand a full accounting of Berenger’s book sales … which they say “should not take long” -- since it's an "absolute bore to read."

Lastly, if Berenger doesn't pull her "literary classic" off shelves immediately ... Omarosa says she will file a lawsuit seeking $150k for each violation of her copyright.

Jacked up Kellan Lutz's biggest muscle might be his heart -- he just hooked up the crew of his new TV show with some serious swag, but he made 'em earn it with an intense pick-up game of cornhole.

We’re told Lutz -- who hosts the new FOX adrenaline junkie show "Bullseye" -- showed up on the last day of shooting and handed out raffle tickets to roughly 100 crew members.

Each person got 3 shots to drop their sack in the hole and win one of the awesome prizes Kellan bought -- including Xboxes, PS4s, iPad Airs, Beats by Dre headphones, 50” TVs, Fitbits and Bluetooth speakers. Total cost to the host (with the most) ... more than $10k, we're told.

The biggest winner of the day might be the craft services woman who scored a 50" Samsung flat screen!

We're told Kellan wanted to thank his co-workers for their hard work shooting the show -- where contestants hurl their bodies (or have it hurled) at a giant bullseye.

Imagine getting paid $60,000 ... just to bang.

That's how much it costs to mate with American Pharoah's father right now ... and the prices are going UP UP UP in the wake of AP dominating at the Kentucky Derby and the Preakness.

The horse that's getting all the action is Pioneerof The Nile -- who's been nailing mares professionally since 2010 ... and churning out some of the fastest ponies in the game.

TMZ Sports spoke with the people at WinStar Farms, where Pioneer lives (and bangs), who tell us ... "The phones have been ringing non-stop with people asking about him [since the Derby]."

When Pioneer first got into the baby making game, his rate was $17,500. But that was in 2010 ... before his kids started crushing it on the track. Now, his seed runs $60k-a-pop and we're told the price is expected to go WAY up.

A rep for Pioneer's owner tells us, "He was busy before. His babies were hitting the ground running. But we haven't experienced anything like this. Not even close."

So, how much higher could the prices go if Pharoah wins the Belmont Stakes and takes the first Triple Crown since 1978?

No one would give us an exact price but they did say it would provide a VERY significant boost.

After all ... "Everybody loves a winner."

Mackenzie McKee wants to turn her mosquito bites into mountains…and, best of all, she wants you to pay for it.

The "Teen Mom 3" star has started a fundraising page on MyFreeImplants.com -- a kickstarter of sorts for boob jobs (who knew?).

According to her crowdfunding profile, McKee – a self-proclaimed fitness nut -- feels going under the knife will make her body “more proportionate” and help her take home gold at fitness and bikini competitions. She's looking to upgrade to a full C cup.

Also, it can't hurt that estranged husband Josh is out of the picture ... since he'd put the kibosh on her boosting her rack.

Mackenzie already has Bev Hills surgeon Dr. Neal Handel on standby -- but she still has a looooong way to go. As of now, she's only tallied up about $20 of her $5k goal.

Lil Wayne and Wiz Khalifa are going into a new business -- DJing -- and they're charging a lot for rank amateurs.

We're told Wayne and Khalifa have been inspired by Snoop's foray into spinning, and they've now set their price ... Wayne will play your songs for $60k and Khalifa is asking a more reasonable $25k.

Of course, they're also demanding the usual perks, including 1st class air travel and VIP treatment.

They've both already booked gigs and are on the hunt for more. Wiz even has a new name -- his DJ name is DJ Daddy Cat.

Bob Arum just put his money where his mouth was -- giving a paparazzo (not ours) a $100 ... to apologize for telling the guy to bet on Manny Pacquiao!!!

Manny's promoter was leaving Craig's in West Hollywood this weekend ... when the photog approached him and reminded him that he told bettors to put their money on PacMan to beat Mayweather.

Obviously, Pacquiao didn't win ... and Bob felt bad ... so he reached into his pocket and PERSONALLY paid the guy back!!!

Animal Planet's "My Cat From Hell" host Jackson Galaxy's former partners want to scratch his eyes out -- legally speaking ... because they say he's cheating them out of thousands.

According to the docs ... consulting producer Brian Rochlin and publicist Susan Mainzer say they had a deal with Galaxy -- he'd give them 10% of his take, and another 15% of any back-end money.

Rochlin and Mainzer say Jackson started shorting them after 3 seasons of dutifully paying. In the suit, they acknowledge it was an oral agreement, but hope the fact he's been paying will prove they had a deal. Plus, they say Jackson emailed them ... it was time to "end this business relationship."

Jackson's ex pawtners want him to pony up for the rest of season 4, all of 5 and 6 -- and if it's picked up ... they also want season 7 dough.
